Abstract: The invention relates to a double-handled fishing-rod reel with a thumb rest. This thumb rest has a flat portion on which the thumb of the angler can be positioned when the fishing reel is in use, and which is attached to one of the struts that serve to keep the two lateral frame plates of the reel a fixed distance apart. The strut in question is arranged above the reel and in front of the axis of the reel. The thumb rest can form an integral whole with the strut. The thumb rest thus formed permits secure retention of the reel in the hand of the angler, improves the reel drive in all directions, and in particular eliminates the cause of pain or fatigue in the thumb of the angler which holds the reel, especially when the fishing-rod reel is held by the thumb for an extended period.

Abstract: A fault point in a line section of a three-phase power transmission line, is determined by measuring currents and voltages at a measuring point arranged adjacent the near end of the section. The type of fault (single-phase/multi-phase ground fault/phase-to-phase fault) is determined and the parameters in a quadratic equation are determined using the relative distance (n) from the measuring point to the fault point as a variable. The equation is derived in advance from the electrical relationships between the complex values of the line impedance, the source impedances of the networks located ahead of and behind the fault, and measured currents and voltages following elimination of the fault resistance and possible zero sequence components. The parameters in the equation are determined by the type of the fault, by the measured voltages and currents and by said impedances. The equation is solved directly by means of a numerical square root method. When calculating the parameters, the fundamental frequency components of the measured values are used, which components are obtained by digital filtering of the measured values.

Abstract: Concentration sensor for fibre suspension in a closed system. Measuring of the concentration in a closed system provides some difficulties. For example, friction variations in supports for the sensor and irregular movements of the fibre suspension may give serious disturbances of the measuring result. Through the present invention these disturbances have been eliminated. In a known way at the side of a suspension containing pipe (1) a niche (2) has been connected having an opening against the pipe. In the niche a rotatable stirrer and a not rotatable sensor have been arranged. The stirrer has its shaft preferably perpendicular against the pipe and near the opening of the niche. The sensor is located behind the stirrer in the niche. The stirrer is rotatable by means of a motor. The sensor has been elastically suspended so that it may be provided a tendency for turning. When the stirrer is rotating it will create a whirl of the suspension in the niche which whirl partly prevents the suspension in the pipe to freely flow into the niche, partly influences the sensor by means of a torque which mirrors the concentration of the suspension, which means that a higher concentration creates a higher torque. The torque of the sensor is measured by means of a shaft or three pins which extend out of the niche through elastic rubber bushings.

Abstract: A modulator arrangement comprises two Mach-Zehnder modulators, a main modulator (2) and a compensation modulator (3) having non-linear transmission functions. The modulators (2, 3) are controlled by a modulating control signal (V), via electrodes (16, 17). A carrier wave (S1) from a laser (7) is power divided (a, 1-a) into part-waves in a power divider (5) between the modulators (2, 3). The modulated part-waves (S2, S3) are superimposed at an output (14) to produce a resultant modulated wave (S4). A linearized transmission function between the control voltage (V) and the power of the resultant modulated wave (S4) has a radius of curvature whose length is maximized within a control voltge range, so as to minimize intermodulation distortion. The mean slope of the transmission function is maximized within this range. At a common control voltage (V) for the modulators (2, 3), the modulator arrangement has an optimal transmission function at a length ratio b =  2ROOT 3:1 between the modulators (2, 3), and a power ratio between the part-waves of  2ROOT 3:9. The main modulator (2) is the shortest and modulates the strongest part-wave.
